Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478378, here are decompositions:

41 + 33478337 = 33478378
47 + 33478331 = 33478378
71 + 33478307 = 33478378
179 + 33478199 = 33478378
251 + 33478127 = 33478378
257 + 33478121 = 33478378
281 + 33478097 = 33478378
317 + 33478061 = 33478378

Showing the first eight; more decompositions exist.
